Gold returned to fellow Italian (5)
I believe the answer is:
roman
'italian' is the definition.
(someone from Rome)
'gold returned to fellow' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'returned' shows that the letters should be reversed in order.
'to fellow' becomes 'man' (fellow can mean a man).
'or' backwards is 'ro'.
'ro'+'man'='ROMAN'
(Other definitions for roman that I've seen before include "Type of candle, nose etc" , "One like Julius Caesar" , "Native to Italian capital" , "European citizen" , "Polanski" .)
